Abstract This paper describes the successful application of Glass Reinforced Epoxy (GRE) casing in 1,100-m water injection wells in Puesto Hernandez field, Argentina. Prior to running 5 1/2-in. casing, thorough testing was carried out to evaluate the actual performance during frac treatments using a surface-mounted model. Other tests were designed and carried out to evaluate casing behavior during running, cementing and perforating operations. Operational aspects, such as the effect of buoyancy, cement logging and downhole tools are addressed, as well as solutions and proposed approaches to remaining problems. To date, four wells have been completed with this technique. Results indicate that casing, tools and operational techniques are appropriate and represent an innovative, sound alternative to reduce maintenance costs associated with scaling and corrosion.
